Tracing the roots of early sexual debut among adolescents in psychiatric care

Objective: To identify the most important social and personal characteristics related to early sexual debut among troubled teenagers. Method: One hundred ninety-eight youths aged 12-19 years were recruited from outpatient mental health clinics and completed self-reports and interviews about their age of sexual debut; family, peer, and partner relationships (e.g., parental hostile control, negative peer influence, need for intimacy); and personal characteristics (e.g., achievement motivation, externalizing problems). Broad-band (externalizing, internalizing) and narrow-band (depression/anxiety, delinquency) psychopathology was assessed with the Youth Self-Report and Child Behavior Checklist. Results: Optimal Data Analysis was used to generate a classification tree model to identify variables associated with whether or not youths initiated oral, vaginal, and/or anal sexual activity before or after age 14. Three social context variables (parental hostile control, negative and positive peer influence) and one personal characteristic (externalizing problems) correctly classified 87.4% of teenagers as initiating sexual activity at less than or equal to14 or >14 years of age. Conclusions: Parental behavior and peer influence were the most important variables associated with the timing of sexual debut. Results support a social-personal framework for understanding sexual risk-taking among adolescents in psychiatric care, and the data offer relatively strong evidence that specific factors could be used to identify troubled teens at risk for early sexual debut.
